3x + 5 = 6x + 23 -3x = 18 x = -6
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
6x-7 = 3x+5 6x = 3x+12 (subtracting -7) 3x=12 (subtracting 3x) x=4 (dividing by 3)
3x - 8 = 7 so x = 5
x = 3/5 and y = 1/5
3x=6x-15 ....you want to take 6x and put it on the other side of the = sign. To do that you do the opposite. So you would subtract since 6x is a positive number. so then the equation is 3x-6x=-15. 3x-6x = -3x which makes the equation -3x=-15. Then you would take -3 which is being multiplied by x and do the opposite operation on the other side. so -3 divided by -15 equals 5. which makes the equation now x=5. So then 5+8=13
34x + 72 is the answer to the equation 12 plus 6x-4 5 plus 2 3x-1.
Solve the equation below for x. If your answer is not a whole number, enter it as a fraction in lowest terms, using the slash mark ( / ) as the fraction bar.3x + 5 = 6x + 23x=-6
6x - 14 = 3x + 5Subtract 3x from each side: 3x - 14 = 5Add 14 to each side: 3x = 19Divide each side by 3: x = 19/3
fx=3x-5 f=(3x-5)/x f2=(6x-10)/x /=divide
3x + 5
From first equation y = 3x + 5. Substitute this in second equation 2(3x + 5) = 6x + 10 This proves that 6x + 10 = 6x + 10 which is not helpful! I suppose possible solutions would be x = 0, y = 5 or x = 1, y = 8 etc etc Are you sure of your two equations, please?
5x^2 + 6x + 9 + (?) = -x^2 +3x + 3 (?) = -5x^2 -6x - 9 -x^2 +3x + 3 = -6x^2 -3x -6 Ans: -6x squared +3x -6
3x = 6x - 15Add 15 to each side:3x + 15 = 6xSubtract 3x from each side:15 = 3xDivide each side by 3:5 = xAdd 8 to each side:13 = x + 8
3x-5=3x+5 There is no solution.
what is a slope
The equivalent expression of 3x-9 plus 3x plus 5 is negative 4.
6x + 4 = 3x + 19 3x + 4 = 19 3x = 15 x = 5 Check it. 30 + 4 = 15 + 19 It checks.
2x(3x + 5)
6x2 + 10x = 2x*(3x + 5)
2(1 - 3x + 6) = -x 14 - 6x = -x 14 - 6x + 6x = -x + 6x 14 = 5x 14/5 =5x/5 14/5 = x
3x+5=20 x=5 since 5x3+5=20
